Want a built trans??
#16
FYI. My 09 ecsb 5.3 Silverado came w a 4l70 from the factory. Only way I found this out was when I had a 60 built and the tranny guy showed me the difference. Then swapped all the good stuff into my 70. Best of both worlds and its holding up great
Some factory freak. I will check my glove box on lunch
